The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the ...
Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [14] and to ecosystems, biodiversity, and natural resources [15] caused directly or indirectly by humans.
Human ecology has a history of focusing attention on humans' impact on the biotic world. [ 1 ] [ 34 ] Paul Sears was an early proponent of applying human ecology, addressing topics aimed at the population explosion of humanity, global resource limits, pollution, and published a comprehensive account on human ecology as a discipline in 1954.
Ecology is as much a biological science as it is a human science. [5] Human ecology is an interdisciplinary investigation into the ecology of our species. "Human ecology may be defined: (1) from a bioecological standpoint as the study of man as the ecological dominant in plant and animal communities and systems; (2) from a bioecological ...
Environmental social science is the broad, transdisciplinary study of interrelations between humans and the natural environment. Environmental social scientists work within and between the fields of anthropology, communication studies, economics, geography, history, political science, psychology, and sociology; and also in the interdisciplinary fields of environmental studies, human ecology ...
Environmental science is an interdisciplinary academic field that integrates physics, biology, meteorology, mathematics and geography (including ecology, chemistry, plant science, zoology, mineralogy, oceanography, limnology, soil science, geology and physical geography, and atmospheric science) to the study of the environment, and the solution of environmental problems.
Biocapacity is the productive area that can regenerate what people demand from nature. Therefore, the metric is a measure of human impact on the environment. As Ecological Footprint accounts measure to what extent human activities operate within the means of our planet, they are a central metric for sustainability.
Ecological overshoot expressed in terms of how many Earths equivalent of natural resources are consumed by humanity each year. Ecological overshoot is the phenomenon which occurs when the demands made on a natural ecosystem exceed its regenerative capacity.
